Abstract

In recent years, two of the most pressing problems in the world have become the rising need for energy and the degradation of the environment. Industrialization’s discharge of organic and metal ion waste into water systems has created a critical demand for efficient removal and degradation of organic waste. Due to their superior optical and electrical properties, semiconductors like metal oxides and mixed metal oxides have attracted a lot of attention for photocatalysis. The majority of these semiconductors, however, lack the ideal band alignment necessary for effective sun/solar light absorption. FeVO4 can be a useful tool for band tuning for visible light photocatalysis in order to get around this problem. Many attempts have been made over the years to increase FeVO4’s photocatalytic performance. It has been postulated and put into practice that a number of different modification strategies, including element doping and composite fabrication, can be utilized to increase the efficiency of photocatalysts based on FeVO4. The photocatalytic degradation of harmful organic pollutants by various metal- and non-metal-doped FeVO4-based materials is highlighted in this review paper. In recent years, significant progress has been made in understanding the core problems and creating effective photocatalysts.

用于降解有机毒物的掺金属和非金属 FeVO4 基复合半导体:综述
摘要 近年来,能源需求不断增加和环境恶化已成为世界上最紧迫的两大问题。随着工业化的发展,有机废物和金属离子废物不断排入水系统,这就对高效去除和降解有机废物提出了更高的要求。由于金属氧化物和混合金属氧化物等半导体具有优越的光学和电学特性,它们在光催化方面引起了广泛关注。然而,这些半导体大多缺乏有效吸收太阳光/太阳能所需的理想带排列。为了解决这一问题,FeVO4 可以成为可见光光催化中进行能带调整的有用工具。多年来,人们为提高 FeVO4 的光催化性能进行了许多尝试。根据推测和实践,可以利用多种不同的改性策略(包括元素掺杂和复合制造)来提高基于 FeVO4 的光催化剂的效率。本文重点介绍了各种金属和非金属掺杂的 FeVO4 基材料对有害有机污染物的光催化降解。近年来,在理解核心问题和创造有效光催化剂方面取得了重大进展。
